Completed gas furnace replacement and new install of humidifier and electrostatic filter. Disconnected and removed the old furnace leaving it for them to keep. Set new furnace on blocks and reconnected the gas, electric, pvc venting and ran new drain hose. Installed a new Aprilaire model 600 humidifier and wired it into the furnace. Installed a new electrostatic filter in the existing space guard box. We are finished with the install but will still need a technician start up.
